THE DANGEROUS MYTH OF GRADE INFLATION That's a Chronicle of Higher Education public access article (no registration required), fisked by Tightly Wound.

The Superintendent has examined Tightly Wound's certificate of convenience and necessity, and recognizes her for interchange privileges.

There may be commentary from the Superintendent on the phenomenon of grade inflation, but not today. Academicians please note the example of the Pacific Coast Talgo trains operated for Amtrak. There are six train sets, meaning no spares for equipment failure. The Spanish manufacturers of those trains are embarrassed that there were six failures in the first few months of operation. Imagine embarrassment at a 99% reliability rate.
